Product Description

The 1/4-20*1-1/2 hex head 1/4-20 fasteners are precision-engineered 1/4-20 UNC bolts designed for robust mechanical fastening in industrial applications. These 1.5-inch machine screws feature a standard hex head for secure torque application using wrenches or sockets, ensuring reliable assembly in machinery, automotive, and construction equipment. Crafted from high-grade steel with optional corrosion-resistant coatings, they operate effectively across temperatures ranging from -40°F to 450°F (-40°C to 232°C) and withstand tensile loads up to 4,200 psi. Ideal for heavy-duty frameworks, their threaded UNC profile ensures compatibility with standard nuts and pre-tapped components. Key advantages include durability, ease of installation, and vibration resistance, though they require periodic inspection in high-stress environments. No electrical interfaces, power requirements, or sensors are integrated.
